Re: [csswg-drafts] [css-anchor-position-1] Which writing-mode does position-try-tactics operate on? (#12869)

Our usual rule for logical keywords (across several properties now) is that the unadorned logical word refers to the container's WM, and self-* refers to the element's own WM. Our few exceptions (which I can't recall off the top of my head) I think are just places where we figured that we'd *never* want to refer to a container, so using the plain logical keyword for the element's own WM was fine.

I suspect we want to lean on that, then - use the containing block's WM, and if we want the element's own directions, use self-*.

(Note that, in this case, I could see us *also* wanting the default anchor's WM, potentially, which would use a different set of prefixes, like `anchor-block`. This would mesh well with using `block` and `self-block`.)
